The SPEEDO is an irreversible electromechanical gear motor for the automation of sliding gates. It is equipped with an electronic control unit and connector for the radio receiver. Electrical connections to external devices have been provided. In the event of a power failure, the SPEEDO will operate on the battery back-up system. The amount of operations possible on the battery back-up is dependent on various factors including condition of the batteries, gate weight, quality of installation and ambient temperature. In the event of prolonged power failure the SPEEDO can be released using the manual release lever in order to move the gate manually.
